An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!!
Answer:
Step-by-step explanation:
Supplementary angles add up to 180°.
“θ is 148° more than its supplement”
Supplement of θ = 180°-θ
θ = (180°-θ) + 148°
2θ = 328°
θ = 164°
Supplement of θ = 180°-164° = 16°

Fred was purchasing rice for his restaurant for the week. He usually makes 150 dishes a week with rice and each portion is 5 ounces. How many pounds of rice should Fred purchase for the week?
Answer: He bought 46.875 pounds of rice for the week.
Step-by-step explanation:
Total rice he bought = (Number of dishes made in a week) x (portion of rice in each dish)
GIven: Each portion has 5 ounces of rice.
i.e. each portion has [tex]\dfrac{5}{16}[/tex] pounds of rice. [ 1 pound = 16 ounces]
Total rice he bought ( in pounds)=[tex]150\times\dfrac{5}{16}[/tex]
[tex]=46.875\text{ pounds}[/tex]
Hence, he bought 46.875 pounds of rice for the week.
Amal's picture is 60 millimeters long. How many
centimeters long is his picture? 10 millimeters = 1
centimeter
Answer:
6 centimeters
Step-by-step explanation:
60 millimeters
10 millimeters = 1 centimeter
How long is the picture in centimeters
______________________________
We know the scale of millimeters to centimeter which is when there are 10 millimeters, 1 centimeter is made. Now we're looking for 60 millimeters, let's see how many times it takes 10 to get to 60.
10 * 6 = 60
So you have to multiply by 6 to find you answer :
1 centimeter * 6
6 centimeters

Step-by-step explanation:
Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Using the similarity theorem f the triangle
(4+6)/x+9 = 4/x
10/x+9 = 4/x
Cross multiply
10x =4(x+9)
10x = 4x+36
10x-4x = 36
6x = 36
x = 6
Hence the value of x is 6
Amy has the cards below:
3, 4, 5, 6, 7, 8
Select the letter that matches the probability of the dice landing on 3:
(diagram in the image attached).
Answer:
B (1/6)
Step-by-step explanation:
The cards she draws doesn't affect what number the dice lands on. 1 every 6 times on average the dice lands on 6 so there is a 1/6 probability represented by B.
25 divided by 100 using long divison
Answer:
4 have a great day (ik it's long but still helps)
Step-by-step explanation:
Here we will show you step-by-step with a detailed explanation of how to calculate 100 divided by 25 using long division.
Before you continue, note that in the problem 100 divided by 25, the numbers are defined as follows:
100 = dividend
25 = divisor
Step 1:
Start by setting it up with the divisor 25 on the left side and the dividend 100 on the right side like this:
2 5 ⟌ 1 0 0
Step 2:
The divisor (25) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
2 5 ⟌ 1 0 0
Step 3:
Multiply the divisor by the result in the previous step (25 x 0 = 0) and write that answer below the dividend.
0
2 5 ⟌ 1 0 0
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
2 5 ⟌ 1 0 0
- 0
1
Step 5:
Move down the 2nd digit of the dividend (0) like this:
0
2 5 ⟌ 1 0 0
- 0
1 0
Step 6:
The divisor (25) goes into the bottom number (10), 0 time(s). Therefore, put 0 on top:
0 0
2 5 ⟌ 1 0 0
- 0
1 0
Step 7:
Multiply the divisor by the result in the previous step (25 x 0 = 0) and write that answer at the bottom:
0 0
2 5 ⟌ 1 0 0
- 0
1 0
0
Step 8:
Subtract the result in the previous step from the number written above it. (10 - 0 = 10) and write the answer at the bottom.
0 0
2 5 ⟌ 1 0 0
- 0
1 0
- 0
1 0
Step 9:
Move down the last digit of the dividend (0) like this:
0 0
2 5 ⟌ 1 0 0
- 0
1 0
- 0
1 0 0
Step 10:
The divisor (25) goes into the bottom number (100), 4 time(s). Therefore put 4 on top:
0 0 4
2 5 ⟌ 1 0 0
- 0
1 0
- 0
1 0 0
Step 11:
Multiply the divisor by the result in the previous step (25 x 4 = 100) and write the answer at the bottom:
0 0 4
2 5 ⟌ 1 0 0
- 0
1 0
- 0
1 0 0
1 0 0
Step 12:
Subtract the result in the previous step from the number written above it. (100 - 100 = 0) and write the answer at the bottom.
0 0 4
2 5 ⟌ 1 0 0
- 0
1 0
- 0
1 0 0
- 1 0 0
0
You are done because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 100 divided by 25 calculated using Long Division is:
4
0 Remainder
Write the equation of the line that passes through the points (-6, 4) and (-3,-2).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y=-2x-8
Step-by-step explanation:
-2-4/-3-(-6)=-6/3=-2
y-4=-2(x-(-6))
y-4=-2(x+6)
y-4=-2x-12
y=-2x-12=4
y=-2x-8

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Gabriella was offered a job after college earning a salary of $50,000.
